We're working on what sounds like the same issue Jason.
We have not confirmed that we can force AMQ to use the OracleJDBCAdapter
but that is our current line.

I'm also investigating why detection is not working. The driver name hasn't
changed so it's not obvious. I have a lead I'm running out right now.
Unfortunately we don't have Oracle in Dev or Test so I'm limited in what I
can do.
